Description

Technical Field

[0001] The utility model belongs to the technical field of sealing pad production equipment, in particular to an automatic gluing device for bulldozer sealing pads. Background Art

[0002] The bulldozer rear axle box is an important part of the bulldozer. It connects the transmission system and drive wheels of the bulldozer and is responsible for transmitting the power of the engine to the drive wheels, enabling the bulldozer to move forward, backward and turn.

[0003] When the bulldozer rear axle box is assembled with other components (including gearboxes, valves, brakes, panels, etc.), in order to ensure the sealing of the assembly, oil sealing will be performed on the joint surface, usually using a combination of sealing gaskets + oil-resistant silicone sealant.

[0004] Oil-resistant silicone sealant: It is a paste made of polydimethylsiloxane as the main raw material, supplemented by cross-linking agents, fillers, plasticizers, coupling agents, and catalysts mixed under vacuum conditions. It reacts with water in the air at room temperature and solidifies to form elastic silicone rubber. It can effectively fill and seal various irregular gaps and holes on the surface, and can be used for oil sealing in engineering machinery.

[0005] The original operation method is: 1. Manually apply oil-resistant silicone sealant to the gasket; 2. Install the gasket to the joint surface of the rear axle box and other components; 3. Install the lifting component to press the gasket and install it on the rear axle box. The process of applying oil-resistant silicone sealant to the gasket requires: applying to the inside of the bolt hole, evenly, all around, and without breakpoints, so as to better ensure the sealing effect, but the actual manual application process cannot guarantee the uniformity and no breakpoint requirements. Mechanical gluing can achieve a large storage of colloids and pre-set the gluing trajectory to solve the unevenness or breakpoints in manual gluing, but there is a need for effective positioning of gaskets of different specifications. Utility Model Content

[0006] In order to solve the problem that sealing pads of different specifications cannot be effectively positioned during mechanical gluing, the utility model provides an automatic gluing device for sealing pads of bulldozers.

[0007] The utility model is realized by the following technical solutions:

[0008] An automatic gluing device for a bulldozer sealing pad comprises a main frame, a mechanical arm base is provided at the inner bottom of the main frame, and a gluing mechanical arm is provided on the mechanical arm base;

[0009] The mechanical arm base is provided with a positioning panel, and the positioning panel is arranged on one side of the glue coating mechanical arm; the positioning panel is provided with a plurality of positioning holes, and the positioning holes are provided with retractable positioning pins, and the positioning pins are provided with a plurality of them;

[0010] The main frame is provided with a start-stop switch for starting the control device.

[0011] The positioning pin that is retracted in the positioning hole can form a matching positioning for sealing gaskets of different specifications; since the positioning pin can be retracted into the positioning hole, after replacing sealing gaskets of different specifications, it will not interfere with the sealing gaskets, which helps to improve the efficiency of mechanical gluing.

[0012] A further improvement of the utility model is that a compression spring and a height locking assembly are provided in the positioning hole; the compression spring is provided between the bottom surface of the positioning pin and the bottom surface of the positioning hole, and the height locking assembly limits the height of the positioning pin when it is retracted into the positioning hole. The compression spring can push the positioning pin outward to the top of the positioning panel to limit the position of the sealing gasket; when the positioning pin is retracted into the positioning hole, the height locking assembly fixes the positioning pin to prevent the pop-up of the positioning pin from interfering with the sealing gasket.

[0013] A further improvement of the utility model is that the bottom surface of the positioning pin is provided with a positioning protrusion b extending into the compression spring, and the inner bottom surface of the positioning hole is provided with a positioning protrusion c extending into the compression spring, which is helpful to achieve the limitation of the compression spring.

[0014] A further improvement of the utility model is that the height locking assembly includes a flat cut surface arranged on the lower side of the positioning pin, a groove is arranged on the upper part of the flat cut surface, and a positioning protrusion a matching with the groove is arranged on the inner wall of the positioning hole. When the positioning pin is in a contracted state in the positioning hole, the positioning protrusion a matches with the groove of the positioning pin to prevent the positioning pin from popping outward; when the positioning pin needs to be ejected outward, the positioning pin is rotated circumferentially so that the flat cut surface is opposite to the positioning protrusion a. Since there is no part in the entire flat cut surface area that contacts with the positioning protrusion a, the positioning pin is ejected to the top of the positioning panel under the action of the compression spring.

[0015] A further improvement of the utility model is that the positioning holes penetrate the positioning panel; the bottom surface of the positioning panel is provided with spring bases having the same number as the positioning holes and capable of covering the positioning holes, and the spring bases are mounted on the positioning panel by screws, which helps to complete the processing and manufacturing of the positioning holes on the positioning panel.

[0016] A further improvement of the utility model is that the above-mentioned glue coating robot arm includes a robot body, and the operating end of the robot body is provided with a glue coating valve, and the glue coating valve is provided with a glue extrusion device connected thereto. The glue extrusion device can realize the functions of temporary storage and outward extrusion of the colloid, and cooperates with the glue coating valve to achieve precise control of the glue output amount.

[0017] A further improvement of the utility model is that a controller is provided on the main frame, and the controller is connected to the gluing mechanical arm and the start-stop switch wire. Different gluing trajectories can be set for sealing pads of different specifications through the controller.

[0018] A further improvement of the utility model is that an indicator light connected to a wire of the controller is provided on the top of the main frame.

[0019] A further improvement of the utility model is that a safety grating connected to the controller wire is provided on the side of the main frame.

[0020] A further improvement of the utility model is that an emergency stop switch connected to the controller wire is provided at the lower part of the main frame.

[0021] It can be seen from the above technical scheme that the beneficial effects of the utility model are: the positioning pin that is retracted in the positioning hole can form a matching positioning for sealing gaskets of different specifications; since the positioning pin can be retracted into the positioning hole, after replacing sealing gaskets of different specifications, it will not interfere with the sealing gaskets, which helps to improve the operating efficiency of mechanical gluing.

The positioning panel 4 is provided with a plurality of positioning holes 403, and a retractable positioning pin 11 is provided in the positioning hole 403, and the positioning pin 11 is provided with a plurality of positioning pins; a compression spring 405 and a height locking assembly are provided in the positioning hole 403; the compression spring 405 is arranged between the bottom surface of the positioning pin 11 and the inner bottom surface of the positioning hole 403, and the height locking assembly limits the height of the positioning pin 11 retracted to the inside of the positioning hole 403. The compression spring 405 can realize the positioning pin 11 to be pushed outward to the top of the positioning panel 4 to realize the position limiting of the sealing gasket; when the positioning pin 11 is retracted into the positioning hole 403, the height locking assembly fixes the positioning pin 11 to prevent the pop-up of the positioning pin 11 from interfering with the sealing gasket.

[0030] The bottom surface of the positioning pin 11 is provided with a positioning protrusion b1103 extending into the compression spring 405 ; the inner bottom surface of the positioning hole 403 is provided with a positioning protrusion c406 extending into the compression spring 405 , which is helpful to achieve the limitation of the compression spring 405 .

[0031] The height locking assembly includes a flat cut surface 1102 disposed on the lower side of the positioning pin 11, a groove 1101 is disposed on the upper part of the flat cut surface 1102, and a positioning protrusion a404 matching with the groove 1101 is disposed on the inner wall of the positioning hole 403. When the positioning pin 11 is in a retracted state in the positioning hole 403, the positioning protrusion a404 matches with the groove 1101 of the positioning pin 11 to prevent the positioning pin 11 from popping outward; when the positioning pin 11 needs to be ejected outward, the positioning pin 11 is rotated circumferentially so that the flat cut surface 1102 is opposite to the positioning protrusion a404. Since there is no part in contact with the positioning protrusion a404 in the entire flat cut surface 1102 area, the positioning pin 11 is ejected to the top of the positioning panel 4 under the action of the compression spring 405.

When the positioning protrusion a404 leaves the groove 1101 and enters the flat cut surface 1102 area, the positioning protrusion a404 can no longer position the positioning pin 11. Under the action of the compression spring 405, the upper part of the positioning pin 11 is exposed from the upper part of the positioning panel 4. To facilitate the rotation of the positioning pin 11, an uneven structure can be provided on the top surface of the positioning pin 11 so that the positioning pin can be moved through the top surface of the positioning pin.

[0038] The positioning pin 11 is pressed back into the positioning hole 403: the positioning pin 11 is pressed downward, and when the positioning protrusion a404 is at the top of the flat section 1102, the positioning pin 11 is rotated so that the positioning protrusion a404 can enter the groove 1101, thereby realizing the axial positioning of the positioning pin 11 in the positioning hole 403.
